Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. The described embodiments are only some, not all, embodiments of the present invention. The components of the embodiments of the invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

At present, mobile POS machines are usually equipped with a battery with a small capacity, however, in actual use, the standby time of the POS machine is required to be longer. In order to reduce the power consumption of the mobile POS machine, in the prior art, the mobile POS machine is usually put into a dormant state when the mobile POS machine is idle. However, when the mobile POS machine is in the dormant state, since the base station does not perform data communication for a long time, the network resources of the mobile POS machine will be released by the base station, and after the mobile POS machine is awakened in the dormant state, it needs to re-establish The connection takes a long time, resulting in prolonged transaction time and reduced transaction efficiency.

For example, in restaurants and other application scenarios where the range of movement is small and transactions are relatively frequent, users usually hope that the time for each transaction should be as short as possible. Therefore, in order to reduce the power consumption of the mobile POS machine, keep the mobile POS machine in a long-term connection state with the base station, and improve the transaction efficiency of the mobile POS machine, an embodiment of the present invention provides a mobile The communication method of the POS machine.

Please refer to FIG. 1 . FIG. 1 is a first schematic flowchart of a communication method for a mobile POS machine provided by an embodiment of the present invention. The execution subject of the method in this embodiment is a communication device of a mobile POS machine, which can be implemented by software and/or hardware, integrated in the mobile POS machine, and is suitable for situations where communication with a base station is required. The communication method of the mobile POS machine as shown in FIG. 1 may include steps S101 to S105.

In S101, the base station identification code of the base station is acquired, and it is checked whether the base station identification code and the sleep wake-up time interval corresponding to the base station identification code are stored in the base station identification code list.

After the mobile POS machine is powered on, it needs to perform network registration first. When the base station determines that the mobile POS machine has network access authority, the mobile POS machine acquires the base station identification code of the base station. For example, the base station obtains the user name and password information of the mobile POS machine when the mobile POS machine is turned on, and determines whether the mobile POS machine has network access authority according to the user name and password information. The base station identification code is used to uniquely identify the base station.

After the mobile POS machine obtains the base station identification code of the base station, it needs to check whether the base station identification code and the corresponding dormancy wake-up time interval of the base station identification code are stored in the list of base station identification codes, so as to When the POS machine enters sleep, the mobile POS machine can be woken up when the sleep time reaches the sleep wake-up time interval corresponding to the base station identification code.

For example, when the mobile POS machine registers with the base station for the first time, the base station identification code of the base station and the corresponding dormancy wake-up function of the base station identification code will not be stored in the base station identification code list of the mobile POS machine. time interval. When the mobile POS machine has been registered with the base station, the base station identification code list of the mobile POS machine may store the base station identification code of the base station and the sleep wake-up time interval corresponding to the base station identification code. Wherein, the sleep wake-up time interval corresponding to the base station identification code may be a sleep wake-up time interval preset by a user, or may be a sleep wake-up time interval obtained by using a dynamic evaluation method.

Wherein, the dormancy wake-up time interval corresponding to the base station identification code refers to the time interval during which the base station reserves network resources for the mobile POS machine when the mobile POS machine is not performing data communication; that is, during the dormancy wake-up time During the interval, the mobile POS machine does not perform data communication, and the base station will not release the network resources allocated to the mobile POS machine.

In S102, if the base station identification code and the sleep wake-up time interval corresponding to the base station identification code are not stored; then preset the sleep wake-up time interval corresponding to the base station identification code as the first sleep wake-up time interval, and The base station establishes a communication connection;

Usually, in order to improve the utilization rate of network resources, the base station will release the network resources allocated to the mobile POS machine and other communication equipment when the communication equipment such as the mobile POS machine does not perform data communication for a long time. For example, when the mobile POS machine enters the dormant state and does not perform data communication, the base station may release the network resources allocated to communication devices such as the mobile POS machine, causing the mobile POS machine to wake up from sleep. Re-establishing a communication connection with the base station prolongs the transaction time of the mobile POS machine and reduces the transaction efficiency of the mobile POS machine. Therefore, after the mobile POS machine is turned on, the present invention first obtains the dormancy wake-up time interval of the mobile POS machine, and then enters dormancy, so that the dormancy time of the mobile POS machine reaches the dormancy wake-up time of the mobile POS machine At intervals, wake up the mobile POS machine and keep the mobile POS machine in communication with the base station.

In some embodiments of the present invention, when the base station identification code and the sleep-wake-up time interval corresponding to the base station identification code are not stored in the base station identification code list, it is necessary to obtain the base station identification code through a dynamic evaluation method. Corresponding hibernation wakeup time interval.

Specifically, first preset the dormancy wake-up time interval corresponding to the base station identification code as the first dormancy wake-up time interval, and establish a communication connection with the base station.

For example, first preset the first sleep wake-up time interval as the maximum sleep wake-up time interval T, and for another example, preset the maximum sleep wake-up time interval T=60min, and then establish a communication connection with the base station. It should be noted that, the value of the maximum sleep-wake-up time interval T is obtained according to actual experience or set according to actual application, which is just an example here, and is not meant to limit the protection scope of the present invention.

Wherein, the establishing a communication connection with the base station includes establishing a PDP connection with the base station or establishing a PPP connection with the base station.

In S103, if the sleep duration reaches the first sleep wake-up time interval, it is detected whether the communication connection with the base station is disconnected.

Since the first dormancy-wake-up time interval is initially the preset maximum dormancy-wake-up time interval T, when the dormancy duration reaches the preset maximum dormancy-wake-up time interval T, the mobile POS machine may have already communicated with The base station disconnects the communication connection, and may still maintain the communication connection with the base station. Therefore, when the sleep duration reaches the first sleep wake-up time interval, it is necessary to detect whether the communication connection with the base station is disconnected.

In S104, if the communication connection is disconnected, shorten the first dormancy wake-up time interval, re-establish a communication connection with the base station, and enter the next dormancy.

When the mobile POS machine is disconnected from the base station, it means that the sleep time of the mobile POS machine is too long, and the base station has released the network resources allocated to the mobile POS machine. Therefore, when the mobile POS machine disconnects the communication connection with the base station, it is necessary to shorten the first dormancy wake-up time interval, re-establish the communication connection with the base station, and then enter the next dormancy. When the dormancy duration of the mobile POS machine reaches the first dormancy wake-up time interval again, it is possible to maintain a communication connection with the base station.

Wherein, the shortening of the first sleep wake-up time interval includes shortening the first sleep wake-up time interval by a fixed time interval, for example, if the fixed time interval is 10 minutes, it means that the sleep time of the mobile POS machine reaches the During the first dormancy wake-up time interval, if the communication connection between the mobile POS machine and the base station is disconnected, shorten the first dormancy wake-up time interval T=T-10min, and re-establish a communication connection with the base station , and then enter the next sleep mode.

In some embodiments of the present invention, the shortening of the first dormancy wake-up time interval may also include shortening the first dormancy wake-up time interval according to a gradient time interval, for example, the gradient time interval is 10min, 10min, 10min . If it is disconnected, shorten the first dormancy wake-up time interval T=T-10min=50min, re-establish a communication connection with the base station, and then enter the next dormancy. When the dormancy time of the mobile POS machine reaches the first dormancy wake-up time interval T=30min, if the communication connection between the mobile POS machine and the base station is disconnected, the first dormancy wake-up time interval T is shortened =T-5min=25min, and re-establish a communication connection with the base station, and then enter the next dormancy, and so on. It should be noted that the gradient time interval can also be other arbitrary gradient time intervals, such as 15min, 10min, 10min, 10min, 5min, 5min, 5min, etc., which are just examples here and are not meant to limit the protection scope of the present invention. limits.

It should be noted that, when S104 is executed, S103 needs to be executed again until if the sleep duration reaches the first sleep wake-up time interval and the communication connection between the mobile POS machine and the base station is not disconnected, step S105 is executed .

In S105, if the communication connection is not disconnected, send a keep-alive message to the network server, so that the base station does not release the network resources of the mobile POS machine, and enters the next dormancy.

When the dormancy duration of the mobile POS machine reaches the first dormancy wake-up time interval, and the communication connection between the mobile POS machine and the base station is not disconnected; it means that the mobile POS machine is at the first dormancy wake-up time In the interval, when data communication is not performed, the base station still reserves network resources for the mobile POS machine. Still carrying out data communication, and reserve network resource for described mobile POS machine, enter next dormancy again.

Wherein, the keep-alive message may be an ICMP message or a message of other protocols, such as a message of the UDP protocol family and the like. The ICMP message is a sub-protocol of the TCP/IP protocol family, and is used to transfer control messages between the IP host and the router. The network server can be a well-known server known to the public, for example, an external network server such as a Google server, a Baidu server, or the like.

It should be noted that, in order to ensure the reliability of the communication connection, after step S105 is executed, S103 can be re-executed, and the sleep duration reaches the first sleep wake-up time interval, and the communication between the mobile POS machine and the base station If the connection is not disconnected, then execute step S105, otherwise execute step S104. In some embodiments of the present invention, when the network resources assigned by the base station are relatively stable, step S105 can also be executed repeatedly after step S105 is executed, without detecting whether the communication connection between the mobile POS machine and the base station is disconnected .

Optionally, as shown in FIG. 2, after step S103, step S201 to step S20 are also included

In S201, if the communication connection with the base station is disconnected, it is judged whether the first sleep wake-up time interval is less than a preset threshold.

For example, the preset threshold is the fixed time interval when the first sleep-wake-up time interval is shortened, or the minimum gradient value in the gradient time interval, or a preset threshold set by other users.

After the first sleep-wake-up time interval is shortened, the dynamic evaluation process of the first sleep-wake-up time interval may be ended by judging whether the first sleep-wake-up time interval is smaller than a preset threshold.

In S202, if the first sleep wake-up time interval is less than a preset threshold, set the first sleep wake-up time interval to zero, and store the base station identification code of the base station and the first sleep wake-up time interval In the list of base station identification codes, go to sleep.

That is to say, when the first dormancy wake-up time interval is shortened to less than a preset threshold, the first dormancy wake-up time interval is directly set to zero, and the base station identification code of the base station and the base station The sleep wake-up time interval T=0 corresponding to the identification code is stored in the base station identification code list, and then enters sleep without pre-establishing a communication connection with the base station.

It should be noted that when the dormancy wake-up time interval T=0 corresponding to the base station identification code, it means that after the mobile POS machine completes data communication with the base station, it will be released by the base station within a relatively short period of time. Therefore, when the sleep-wake-up time interval corresponding to the base station identification code is T=0, it is not necessary to establish a communication connection with the base station in advance, but to establish a communication connection with the base station during data communication. For example, when the mobile POS is turned off and turned on again, the base station identification code and the sleep wake-up time interval T=0 corresponding to the base station identification code are obtained from the list of base station identification codes according to the obtained base station identification code. , it directly enters dormancy without establishing a communication connection with the base station in advance. Only when the mobile POS machine is woken up to perform data communication, it establishes a communication connection with the base station, and disconnects the communication connection with the base station after the data communication is completed.

Optionally, after sending the keep-alive message to the network server if the communication connection is not disconnected, it further includes: storing the base station identification code of the base station and the first dormancy wake-up time interval in the base station identification code. code list.

The base station identification code of the base station and the first dormancy wake-up time interval are stored in the base station identification code list, so that after the mobile POS is turned off, when it is turned on again, it can be obtained from the base station identification code according to the acquired base station identification code. Obtain the base station identification code and the dormancy wake-up time interval corresponding to the base station identification code from the base station identification code list, so as to wake up during the dormancy process and make the base station reserve network resources for the mobile POS machine.

In some embodiments of the present invention, as shown in FIG. 3 , step S106 is further included after the step S101.

In S106, if the base station identification code list stores the base station identification code and the sleep wake-up time interval corresponding to the base station identification code; then establish a communication connection with the base station; the sleep duration reaches the sleep wake-up time At intervals, send a keep-alive message to the network server, so that the base station does not release the allocated network resources, and enters the next dormancy.

In some embodiments of the present invention, as shown in FIG. 4 , if the base station identification code list stores the base station identification code and the sleep wake-up time interval corresponding to the base station identification code, it further includes steps S107 to S109 .

In S107, it is judged whether the sleep-wake-up time interval corresponding to the base station identification code is zero.

That is to say, it is judged whether the dormancy and wake-up time interval corresponding to the base station identification code stored in the base station identification code list is zero, and if it is zero, it means that after the mobile POS machine completes the data communication with the base station, The allocated network resources are released by the base station within a relatively short period of time. Therefore, step S108 is executed, and if the dormancy wake-up time interval corresponding to the base station identification code is zero, it enters dormancy; A communication connection is established, but a communication connection is established with the base station when performing data communication.

If the dormancy wake-up time interval corresponding to the base station identification code is not zero, it means that after the mobile POS machine completes data communication with the base station, the allocated network resources will not be released by the base station within a relatively short period of time, Therefore, step S109 can be executed, if the sleep wake-up time interval corresponding to the base station identification code is not zero, when the sleep duration reaches the sleep wake-up time interval, send a keep-alive message to the network server, so that the base station The allocated network resources are not released, and the next sleep is entered.

In the embodiment of the present invention, when the base station identification code and the dormancy wake-up time interval corresponding to the base station identification code are not stored in the base station identification code list, dynamically obtain the communication connection between the mobile POS machine and the base station. The first dormancy wake-up time interval when it is turned on, and when the dormancy duration reaches the first dormancy wake-up time interval, send a keep-alive message to the network server, so that the base station does not release the network resources of the mobile POS machine, and enters the Hibernate next time. The mobile POS machine can not only reduce power consumption by entering dormancy, but also make the base station not release the network resources of the mobile POS machine during the dormancy process, which solves the problem that the mobile POS machine in the prior art is in a dormant state. After being awakened, the connection with the base station needs to be re-established, and the problem of low transaction efficiency improves the transaction efficiency of the mobile POS machine.
